BREEICHIKZOA-DING FIRE-ARM.

SPECIFICATION formingpart of Letters Patent No. 248,249, dated October 11, 1881.

' Application filed September 12, 1881. (Mode-Ll To all whom it may concern:

vBe it known that 1, WILLIAM H. BAKER, of

Syracuse. in the county of Onondaga and State ,of New York, have invented certain new and useful Improvements in Breech-Loading Fire- Arm s, fully described hereinaftertand represented in the accompanying drawings, in which- Figure 1 represents a sectional side view,

and Fig. 2 a perspective view, of the lockingbolt and operating-tum blers by which the barrels of drop-down guns are locked to the frame in firing position.

Myinvention relates particularly to thatclass of arms known as drop-down guus; audit consists in the means foroperating the locking-bolt by which the barrels are locked in firing position.

Heretofore the locking-bolt has been operated by a top lever and a single rotating shaft or tumbler connected in various ways with the bolt; but I have found this objectionable inarms having outsidehammers, for the reason that when the hammers are cocked the movement of the lever is limited to such an extent that the requisite throw for unlocking the barrels cannot be had. My invention consists, specifically, in the combination and arrangement of two shafts or tumblers connected together-and to the locking-bolt in sucha manner that by a comparatively slight movement .of the operating-1cver a greater movement of the locking-bolt is attained, as will be hereinafter particularly pointed out. 7

Referring to the drawings, A is the operating-lever, connected to the shaft of a tumbler, B, which is located directly below the top strap of the frame. Said tumbler B has an arm, a, which is connected to an arm, I), of a second shalt or tumbler, (J, by a link-connection, as shown clearly in Fig. 2. The shaft or tumbler C has a. second arm, 0, which is connected by a link, (1, with the lockin'gbolt E, which looks the arm a is greater than that of the arm I),

and consequently a given movement of the le ver A will cause a correspondingly greater rotative movement of shaftO, and consequently the throw of the locking-bolt E will also be greater than if the bolt were connected directly to the tumbler B.

In order to provide for the more compact a-rrangement of parts, thejournals of shaft 0 are ecceutrically arranged, as shown in Fig. 2, so that the rotation of said shaft will carry it bodily sidewise in the direction of the movement of the arm a. In this manner the two tumblers can be arranged closer together and sntficient movement of the lever A permitted to impart the necessary movement to the locking-bolt E to lock and unlock the barrels.

A spring, e, is arranged below the top strap or tang of the frame, so as to bearaginst the tumbler B and return the action to its locking position. If preferred, the spring may be arranged to bear against the shaft (3, or directly against the locking-bolt E.

Having thus described my invention, what I claim as new is- 1. A lockingmechanism for drop-down guns,

consisting of two tumblers, as B 0, arranged as shown, and provided with arms a 1), connected together by a link-connection, and a locking-bolt, E, connected to the tumbler C by a coupling, 0 d, substantially as shown and described.

2. The combination of the locking-bolt E, the vertical shaft or tumbler (3, provided with eccentric journals, and connected, as shown, with the bolt E, and an operating-lever and tumbler, 13, connected with the shaft or tumbler O, as shown and described.
